Validity of the Generalized Second Law of Thermodynamics of the Universe Bounded by the Event Horizon in Holographic Dark Energy Model

TL;DR

This paper examines whether the generalized second law of thermodynamics holds for a universe modeled with holographic dark energy bounded by the event horizon, assuming a homogeneous, isotropic universe with non-interacting fluids.

Contribution

It analyzes the validity of the generalized second law in a specific holographic dark energy universe model with non-interacting fluids and an assumed first law.

Findings

The generalized second law holds under certain conditions.

The universe's thermodynamic behavior aligns with holographic dark energy assumptions.

The model supports thermodynamic consistency in cosmological scenarios.

Abstract

In this letter, we investigate the validity of the generalized second law of thermodynamics of the universe bounded by the event horizon in the holographic dark energy model. The universe is chosen to be homogeneous and isotropic and the validity of the first law has been assumed here. The matter in the universe is taken in the form of non-interacting two fluid system- one component is the holographic dark energy model and the other component is in the form of dust.
